commit dca5244d2f5b94f1809f0c02a549edf41ccd5493 upstream.
GCC versions >= 4.9 and < 5.1 have been shown to emit memory references
beyond the stack pointer, resulting in memory corruption if an interrupt
is taken after the stack pointer has been adjusted but before the
reference has been executed. This leads to subtle, infrequent data
corruption such as the EXT4 problems reported by Russell King at the
link below.
Life is too short for buggy compilers, so raise the minimum GCC version
required by arm64 to 5.1.

commit f6351c3f1c27c80535d76cac2299aec44c36291e upstream.
The old way of changing the conntrack hashsize runtime was through changing
the module param via file /sys/module/nf_conntrack/parameters/hashsize. This
was extended to sysctl change in commit 3183ab8997a4 ("netfilter: conntrack:
allow increasing bucket size via sysctl too").
The commit introduced second "user" variable nf_conntrack_htable_size_user
which shadow actual variable nf_conntrack_htable_size. When hashsize is
changed via module param this "user" variable isn't updated. This results in
sysctl net/netfilter/nf_conntrack_buckets shows the wrong value when users
update via the old way.
This patch fix the issue by always updating "user" variable when reading the
proc file. This will take care of changes to the actual variable without
sysctl need to be aware.

commit 8ff60eb052eeba95cfb3efe16b08c9199f8121cf upstream.
acquire_slab() fails if there is contention on the freelist of the page
(probably because some other CPU is concurrently freeing an object from
the page). In that case, it might make sense to look for a different page
(since there might be more remote frees to the page from other CPUs, and
we don't want contention on struct page).
However, the current code accidentally stops looking at the partial list
completely in that case. Especially on kernels without CONFIG_NUMA set,
this means that get_partial() fails and new_slab_objects() falls back to
new_slab(), allocating new pages. This could lead to an unnecessary
increase in memory fragmentation.

commit 00cb645fd7e29bdd20967cd20fa8f77bcdf422f9 upstream.
Commit 25b4620ee822 ("drm/i915/dsi: Skip delays for v3 VBTs in vid-mode")
added an intel_dsi_msleep() helper which skips sleeping if the
MIPI-sequences have a version of 3 or newer and the panel is in vid-mode;
and it moved a bunch of msleep-s over to this new helper.
This was based on my reading of the big comment around line 730 which
starts with "Panel enable/disable sequences from the VBT spec.",
where the "v3 video mode seq" column does not have any wait t# entries.
Given that this code has been used on a lot of different devices without
issues until now, it seems that my interpretation of the spec here is
mostly correct.
But now I have encountered one device, an Acer Aspire Switch 10 E
SW3-016, where the panel will not light up unless we do actually honor the
panel_on_delay after exexuting the MIPI_SEQ_PANEL_ON sequence.
What seems to set this model apart is that it is lacking a
MIPI_SEQ_DEASSERT_RESET sequence, which is where the power-on
delay usually happens.
Fix the panel not lighting up on this model by using an unconditional
msleep(panel_on_delay) instead of intel_dsi_msleep() when there is
no MIPI_SEQ_DEASSERT_RESET sequence.

commit 869c4d5eb1e6fbda66aa790c48bdb946d71494a0 upstream.
The function bnxt_get_ulp_stat_ctxs() does not count the stats contexts
used by the RDMA driver correctly when the RDMA driver is freeing the
MSIX vectors. It assumes that if the RDMA driver is registered, the
additional stats contexts will be needed. This is not true when the
RDMA driver is about to unregister and frees the MSIX vectors.
This slight error leads to over accouting of the stats contexts needed
after the RDMA driver has unloaded. This will cause some firmware
warning and error messages in dmesg during subsequent config. changes
or ifdown/ifup.
Fix it by properly accouting for extra stats contexts only if the
RDMA driver is registered and MSIX vectors have been successfully
requested.

Since multipage bvecs support, bvecs can split in the middle
which means that when we account for the last bvec send we
should also take the iov_iter byte count cap as it might be
lower than the last bvec size.

Because of this, when DPCM finds a BE it does everything it needs on the

is no actual endpoint after the BE.
On meson-axg HWs, the loopback is a special DAI of the tdm-interface BE.
It is only linked to the dummy codec since there no actual HW after it.
>From the DAPM perspective, the DAI has no endpoint. Because of this, the TDM

We are not guaranteed the locking environment that would prevent
dentry getting renamed right under us. And it's possible for
old long name to be freed after rename, leading to UAF here.

commit 5501e9229a80d95a1ea68609f44c447a75d23ed5 upstream.
In some cases, the number of cpus (nr_cpus_online) is confused with the
maximum cpu number (nr_cpus_avail), which results in the error in the
example below:
Example on system with 8 cpus:
Before:
# echo 0 > /sys/devices/system/cpu/cpu2/online
# ./perf record --kcore -e intel_pt// taskset --cpu-list 7 uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.147 MB perf.data ]
# ./perf script --itrace=e
Requested CPU 7 too large. Consider raising MAX_NR_CPUS
0x25908 [0x8]: failed to process type: 68 [Invalid argument]
After:
# ./perf script --itrace=e
#
Fixes: 8c7274691f0d ("perf machine: Replace MAX_NR_CPUS with perf_env::nr_cpus_online")
Fixes: 7df4e36a4785 ("perf session: Replace MAX_NR_CPUS with perf_env::nr_cpus_online")

[ Upstream commit 9ceb7863537748c67fa43ac4f2f565819bbd36e4 ]
When a queue is in NVMET_RDMA_Q_CONNECTING state, it may has some
requests at rsp_wait_list. In case a disconnect occurs at this
state, no one will empty this list and will return the requests to
free_rsps list. Normally nvmet_rdma_queue_established() free those
requests after moving the queue to NVMET_RDMA_Q_LIVE state, but in
this case __nvmet_rdma_queue_disconnect() is called before. The
crash happens at nvmet_rdma_free_rsps() when calling
list_del(&rsp->free_list), because the request exists only at
the wait list. To fix the issue, simply clear rsp_wait_list when
destroying the queue.

BFQ computes number of tags it allows to be allocated for each request type
based on tag bitmap. However it uses 1 << bitmap.shift as number of
available tags which is wrong. 'shift' is just an internal bitmap value
containing logarithm of how many bits bitmap uses in each bitmap word.
Thus number of tags allowed for some request types can be far to low.
Use proper bitmap.depth which has the number of tags instead.

Older versions of BSD awk are fussy about the order of '-v' and '-f'
flags, and require a space after the flag name. This causes build
failures on platforms with an old awk, such as macOS and NetBSD.
Since GNU awk and modern versions of BSD awk (distributed with
FreeBSD/OpenBSD) are fine with either form, the definition of
'cmd_unroll' can be trivially tweaked to let the lib/raid6 Makefile
work with both old and new awk flag dialects.

Table 8-53 in the QUICC Engine Reference manual shows definitions of
fields up to a size of 192 bytes, not just 128. But in table 8-111,
one does find the text
Base Address of the Global Transmitter Parameter RAM Page. [...]
The user needs to allocate 128 bytes for this page. The address must
be aligned to the page size.
I've checked both rev. 7 (11/2015) and rev. 9 (05/2018) of the manual;
they both have this inconsistency (and the table numbers are the
same).
Adding a bit of debug printing, on my board the struct
ucc_geth_tx_global_pram is allocated at offset 0x880, while
the (opaque) ucc_geth_thread_data_tx gets allocated immediately
afterwards, at 0x900. So whatever the engine writes into the thread
data overlaps with the tail of the global tx pram (and devmem says
that something does get written during a simple ping).
I haven't observed any failure that could be attributed to this, but
it seems to be the kind of thing that would be extremely hard to
debug. So extend the struct definition so that we do allocate 192
bytes.
